We successfully synthesized hollow mesoporous silica(HMS) by sol-gel process using charged polymer template. For preparation of HMS, we synthesized charged PS nanospheres . It was monodispersed and controllable by adjust amount of comonomer [2-(methacyloxy)ethyl] trimethyl ammonium chloride, MOTAC. Using this hard template, silica precursor TEOS and pore structure agent CTAB were cooperative self-assemblied and this sol was led to surface of (+) charged polymer and structured organic core/ inorganic shell hybrid particles. Finally HMS were prepared by calcinations at 600℃. Also we could tailored the size of this particles by control of polymer template size. |
